In 1969, a group of scientists concerned with the health hazards posed by environmental mutagens formed the Environmental Mutagen Society to encourage interest in and the study of mutagens in the human environment. In order to deal effectively with this potential health problem, these scientists saw the need for a centralized source of published information on chemicals tested for mutagenicity ...

Relativistic electron losses in Earth's radiation belts are usually attributed to resonant scattering by electromagnetic waves. One of the most important wave mode for such is ion cyclotron (EMIC) mode. Within quasi-linear diffusion framework, resonance relativistic electrons with EMIC waves results very fast precipitation atmosphere. However, intensities often exceed threshold nonlinear intera...

PURPOSE The Ministry of Health and Welfare recently designated 35 major trauma-specified centers (MTSC). The purpose of this study is to determine changes in patient flow and designated hospitals, and to describe the role of the emergency medical information center (EMIC) in a regional trauma care system. METHODS Data of trauma patient inter-facility transfer arrangement by one EMIC were revi...

A new method for color reduction in a digital image is proposed, which is based on the development of a new neural network classifier and on a new method for Estimation of the Most Important Classes (EMIC). The proposed neural network combines the features of the well-known Growing Neural Gas (GNG) and the Kohonen Self-Organized Feature Map (KSOFM) neural networks. We call the new neural networ...

A recent event study suggested a coupling process whereby suprathermal protons (10–100 eV), as result of perpendicular heating by pre-existing magnetosonic waves, can excite electromagnetic ion cyclotron (EMIC) waves with frequency near the local proton (f~0.95fcp). The present tests this process. First, one-dimensional hybrid (kinetic ions/massless fluid electrons) simulations parallel-propaga...

Four years ago Congress made the first appropriation for "medical, nursing, and hospital maternity and infant care for wives and infants of enlisted men in the armed forces of the United States of the fourth, fifth, sixth, or seventh grades." The following month, April 1943, plans for the operation of the Emergency Maternity and Infant Care (EMIC) program were approved by the Children's Bureau ...

Background: The increased carotid intima-media thickness (CIMT) correlates with the presence of atherosclerosis in adults and describes vascular abnormalities in both hypertensive children and adolescents. Objective: To assess CIMT as an early marker of atherosclerosis and vascular damage in hypertensive children and adolescents compared with non-hypertensive controls and to evaluate the infl...

This article describes emic and etic approaches to measurement in terms of a process of associating indicators and constructs. In this process, it is important to establish evidence of an adequate range of indicators and a relevant association of indicators and constructs and to recognize that such evidence places bounds on the interpretation of measurement outcomes. A passage from one of P. L....
